Crawl-space moisture investigation — Damp proofing specialist
Describe musty odours, floor concerns or known standing water and identify the access arrangement without entering an unsafe void. Provide the building type and any previous insulation, drainage or plumbing work so the provider can plan the inspection and relevant specialist involvement.
Service scope
Investigation of moisture affecting underfloor voids or crawl spaces and their adjoining building elements. Ground conditions, drainage, leaks, ventilation and timber condition may interact; entry, treatment and insulation decisions require assessment of the particular void rather than a universal encapsulation prescription.
What is normally included
- Accessible void and moisture-history assessment
- Review of drainage and ventilation interfaces
- Recommendations for specialist follow-up or remedial work
What is not included
- Customer entry into unsafe or restricted voids
- Diagnosis of timber decay or structural capacity from damp appearance alone
Typical tasks
- Plan safe inspection access
- Review visible moisture and services
- Examine ventilation and drainage context
- Identify timber or other specialist concerns
- Set out a staged remedial scope
What to include in your brief
- Void access location and dimensions if known
- Floor and building construction
- Reported symptoms
- Previous insulation or repair work
- Known standing water or leaks
Choosing the right professional
Ask how inspection access will be managed and how the provider distinguishes moisture control from structural or timber treatment. Compare proposals on the investigated cause, not a standard package that assumes every underfloor void needs the same membrane or vent arrangement.
Important considerations
- Restricted access can conceal the extent of defects
- Timber or services may need separate specialist assessment
